BEFORE OPERATING

1. NEVER allow children to operate this riding mower.

Do not allow adults to operate this machine without

proper instructions.

2. DO NOT mow when children and/or others are

present. Keep children out of the mowing area and in

the watchful care of a responsible adult other than the

operator. Be alert and turn machine off if a child

enters the area.

3. The owner/user can prevent and is responsible for

accidents or injuries occuring to themselves, other

people or property.

4. Clear the area to be mowed of objects that could be

picked up and thrown by the cutter blades.

5. DO NOT carry passengers.

6. DO NOT operate the machine under the influence of

alcohol or drugs.

7. Fill the fuel tank with clean, fresh gasoline, with a

minimum octane rating of 87. To avoid personal

injury or property damage, use extreme care in

handling gasoline. Gasoline is extremely flammable

and the vapors are explosive.

A. Extinguish all cigarettes, cigars, pipes and other

sources of ignition.

B. Use only an approved gasoline container.

C. Never remove the gas cap or add fuel with the

engine running. Allow the engine to cool before

fueling.

D. Never fuel the machine indoors or in an enclosed

trailer.

E. Never store the machine or fuel container where

there is an open flame , spark or pilot light such as

on a water heater or other appliances.

F. Never fill containers inside a vehicle or on a truck

or trailer bed with a plastic liner. Always place

containers on the ground away from your vehicle

before filling.

G. Remove the machine from the truck or trailer and

fuel on the ground. If this is not possible, then

refuel the machine with a portable container,

rather than from a gasoline dispenser nozzle.

H. Keep the nozzle in contact with the rim of fuel

tank or container opening at all times until fueling

is complete. Do not use a nozzle lock-open

device.

I. If fuel is spilled on clothing, change clothing

immediately.

J. Replace gas cap and tighten securely.

8. If the operator(s) or mechanic(s) cannot read English

or Spanish, it is the owner's responsibility to explain

this material to them.

9. DO NOT wear loose fitting clothing that could get

tangled in moving parts. Do not operate the machine

wearing shorts; always wear adequate protective

clothing including long pants. Wearing safety glasses,

safety shoes and a helmet is advisable and is required

by some local ordinances and insurance regulations.

10. Operator hearing protection is recommended,

particularly for continuous operation of the mower.

Wear suitable hearing protection. Prolonged

exposure to loud noise can cause hearing impairment

or loss.

11. Keep the machine and attachments in good operating

condition. Keep all shields and safety devices in

place. If a shield, safety device or decal is defective

or damaged, repair or replace it before operating the

machine.

12. Be sure the safety switches are functioning correctly.

13. USE ONLY SCAG APPROVED

ATTACHMENTS AND ACCESSORIES.

Attachments and accessories manufactured by

companies other than Scag Power Equipment are not

approved for use on this machine. Scag approved

attachments and accessories:

Cup Holder (p/n 9240)

10. Keep hands and feet away from cutting units.

11. Shut the engine off and wait until the blades come

to a complete stop before removing the grass

catcher container.

12. Never raise the cutter deck while the blades are

rotating.

13. Always park the mower and/or start the engine on

a level surface. Apply the parking brake to

prevent the mower from moving when you are not

in the operator’s position.

14. If the cutting blades should strike a solid object or

the equipment should start to vibrate abnormally,

stop the engine, disconnect the spark plug wires,

and check immediately for the cause. Vibration is

generally a warning of trouble. Check the machine

for damaged or defective parts. Repair any

damage before starting the engine or operating the

cutter deck. Be sure the blades are in good

condition and the blade bolts are tight.

15. Reduce speed and exercise extreme caution on

slopes and in sharp turns to prevent tipping or loss

of control. Be especially cautious when changing

directions on slopes.

DO NOT operate on steep slopes. To check a

slope, attempt to back up it (with the cutter deck

down). If the machine can back up the slope

without the wheels slipping, reduce speed and

use extreme caution. ALWAYS FOLLOW OSHA

APPROVED OPERATION.

16. Use care when approaching blind corners, shrubs,

trees, or other objects that may obscure vision.

17. Do not touch the engine or muffler while the engine

is running or soon after it is stopped. These areas

could be hot enough to cause a burn.

WARNING:

WHILE OPERATING

1. Start the engine when the cutter blades are disen-

gaged, the parking brake is on and the right foot

pedal is in the neutral position. Only start the

engine from the operators position.

2. Do not run the engine in a confined area without

adequate ventilation. Exhaust fumes are hazardous

and could possibly be deadly.

3. Use care when loading or unloading the machine

onto a trailer or truck.

4. Look behind and down before backing up to be

sure of a clear path.

5. Using the machine demands attention. To

prevent loss of control:

A. Mow only in daylight or when there is good

artificial light.

B. Watch for holes or other hidden hazards.

C. Do not drive close to a drop-off, ditch, creek

bank, or other hazard.

E. Do not operate where conditions are slippery.

6. The discharge chute must always be installed and

in the down position on the side discharge cutter

deck except when the mulching plate or Hurricane

Mulch Kit are properly installed. If the discharge

area should plug, shut the engine off and wait for

all movement to stop before removing the obstruc-

tion.

7. NEVER operate with the PTO shield, or other

guards not securely in place. Be sure all inter-

locks area attached, adjusted and funcioning

properly.

8. Disengage the blades and wait for them to stop

before crossing gravel drives, walks or roads.

9. Be aware of discharge direction and do not point

at anyone.

MAINTENANCE AND STORAGE

1. Disconnect the spark plug wire from the spark

plug to prevent accidental starting of the engine

when servicing, adjusting or storing the machine.

2. If the mower must be tipped to perform mainte-

nance or adjustment, remove the battery, drain

the gasoline from the fuel tank and the oil from

the crankcase. Use jack stands to support the

machine when required.

3. To reduce potential fire hazard, keep the engine

free of excessive grease, grass, leaves and accu-

mulations of dirt.

4. Park the machine on level ground. Never allow

untrained personnel to service the machine.

5. Disconnect battery or remove spark plug wires

before making any repairs. Disconnect the negative

terminal first and the positive last. Reconnect

positive first and negative last.

6. Use care when checking blades. Wrap the blades

or wear gloves and use caution when servicing them.

Only replace blades. Never straighten or weld

them.

19. Do not pass or stand on the grass discharge side

of any mower with the engine running. Stop the

cutter blades when another person approaches.

Battery posts, terminals, and related accessories

contain lead and lead compounds, chemicals

known to the State of California to cause cancer

and reproductive harm. Wash hands after

handling.

WARNING:

18. Before leaving the operator’s position or leaving

the mower unattended, move the right foot pedal

into the neutral position, apply the parking brake,

and move the blade engagement switch to OFF.

Shut the engine OFF and remove the key.

7. Be sure the machine is in safe operating condition by

keeping nuts, bolts, and screws tight. Check the

blade mounting bolts and nuts frequently to be sure

they are tightened.

8. If the engine must be running to perform a mainte-

nance adjustment, keep hands, feet, clothing and

other parts of the body away from the cutter deck

blades and other moving parts.

9. Do not overspeed the engine by changing governor

settings. To be sure of safety and accuracy, have an

authorized dealer check maximum engine speed with

a tachometer.

10. The engine must be shut off before checking the oil

or adding oil to the crankcase.

11. Allow the engine to cool before storing the mower in

any enclosure such as a garage or storage shed.

Make sure the fuel tank is empty if the machine is to

be stored in excess of 30 days. Do not store the

mower near any open flame or where gasoline fumes

may be ignited by a spark.

12. Always store gasoline in a safety-approved, red

container.

13. Be careful when servicing the battery as it contains

acid, which is corrosive and could cause burns to

skin and clothing.

14. Batteries release explosive gases when being

charged or discharged. Keep batteries away from

any source of sparks and/or flame. Charge batter-

ies in an open, well ventilated area.

15. Make sure all hydraulic connections are tight and all

hydraulic hoses and lines are in good condition

before starting the machine.

Hydraulic fluid is under high pressure. Keep

body and hands away from pinholes or nozzles that

eject hydraulic fluid under high pressure. If you need

service on your hydraulic system, please see your

authorized Scag dealer. If hydraulic fluid is injected

into the skin, it must be surgically removed within a

few hours by a doctor or gangrene may result.

INITIAL RUN-IN PROCEDURES

(FIRST DAY OF USE OR APPROXI-

MATELY 10 HOURS)

1. Check the belts for proper tension at 2, 4 and 8

hours. Adjust as needed. (See Belt Tension,

page 9).

2. Check the neutral adjustment. (See Adjust-

ments, page 8)

3. Check the tires for proper pressure.

Caster Wheels Flat Free

Drive Wheels 12 psi

Rear Steering Wheel 15 psi

WARNING:

4. Check for loose hardware. Tighten as needed.

5. Check the safety switches for proper adjustment:

* The engine should crank and start if the

machine is in neutral, the PTO engagement

switch is OFF and the parking brake is ON.

7. Apply lubricant to all the grease fittings. Lubricant

was applied at the factory. This is just a precaution-

ary check to make sure that all the fittings have been

lubricated.

gasoline.

* Open the fuel valve on the bottom of the

fuel tank.

390S0138

PULL UP TO ENGAGE

PUSH DOWN TO DISENGAGE

-NOTE-

When the PTO is engaged or (possibly) disen-

gaged, a squealing sound from the underside of

the machine is normal. It is caused by the

electric clutch plates meshing as the cutter

blades come up to speed. For best equipment

life, engage the clutch with the engine at 3/4

throttle, not under full load.

If you are not familiar with the operation of the

hydrostatic drive, practice turning and

maneuvering before engaging the cutter blades.

5. Release the parking brake. Depress the right foot

pedal at the toe end to drive forward (See Figure 1)

or depress the pedal at the heel end to drive in

reverse. (See Figure 2)

-NOTE-

The left side operator presence pedal must be

depressed for operation.

6. When driving over curbs, disengage the cutter

blades and raise the cutter deck to clear the curb.

Drive forward over the curb. After the curb is

clear, lower the cutter deck back to normal

operating position. Be sure to leave slack in the

cable after lowering the cutter deck.

7. To "freewheel" or move the machine around

without the engine running, rotate the dump valve

lever located on the left rear of the engine deck to

the freewheel position (See Figure 3). The lever

must be returned to the drive position to operate

the machine.

ADJUSTMENTS

PARKING BRAKE

Minor brake adjustments can be made by loosening

the top nut on both brake cables (see Figure 4).

Back the nuts off approximately 1/4". While pulling

one cable downward, tighten the bottom nut on the

cable until it touches the bottom of the brake cable

mount. Tighten both the top and bottom nuts to

lock the cable in place. Repeat the above steps for

the second brake cable. Make sure that both

cables are adjusted evenly so that the brakes do not

cause the mower to pull to the left or right.

-NOTE-

This is a minor brake adjustment. If the

brakes do not function properly after this

adjustment, see your Scag Service Dealer

before operating your mower.

NEUTRAL ADJUSTMENT

1. Set the engine deck up on jack stands so the wheels

are free to rotate.

2. Block the caster wheels to prevent an accident

should the machine fall off the jack stands.

3. Start the engine and determine if the drive wheels

rotate.

Depress Heel End of Pedal

If the drive wheels consistently rotate when foot

pedal control is in neutral, go to step 4.

If the drive wheels inconsistently rotate, i.e. drive

wheels sometimes rotate and sometimes do not

when foot pedal is not depressed, then check

neutral adjustment bolt for "zero free play" in neutral

control spring.

-NOTE-

If there is free play in the foot pedal have your

SCAG servicing dealer inspect the machine and

repair it as needed.

4. If the drive wheels rotate in the forward travel

direction, turn the adjustment bolt clockwise until the

tire rotation stops. If the drive wheels rotate in the

backward travel direction, turn the adjustment bolt

counter-clockwise until the tire rotation stops (See

Figure 5).

5. Check the adjustment of the right foot control pedal

for full forward speed. The pedal should rest on the

foot plate when the pump is stroked in the full

forward position. To make an adjustment, discon-

nect the ball joint from the pedal arm and loosen the

jam nut (See Figure 6). Place the foot control pedal

forward against the foot rest and adjust the ball joint

on the rod until the stud aligns with the hole in the

arm. Bolt the ball joint to the arm and tighten the

jam nut.

6. Start the engine. The wheels should rotate only

when the foot control pedal is depressed.

BELT TENSION

Stop engine and remove the key from the ignition

before making any adjustments. Wait for all

moving parts to come to a complete stop before

beginning work.

-NOTE-

The Hydro Drive Belt is spring-loaded and

does not require adjustment.

To adjust cutter deck drive and blade belts:

1. Remove belt cover.

CAUTION:

Adjust the tension by tightening or loosening

the nut on the J-bolt. (See Figure 9).

4. Replace the belt covers.

BELT ALIGNMENT

Belt alignment is important for proper performance of

your Scag mower. If you experience frequent belt wear

or breakage, see your authorized Scag Service Dealer

for belt adjustment.

CUTTER DECK ADJUSTMENTS

Due to the many conditions that exist, it is difficult to

suggest a setting that will work for every lawn. There

are, however, two adjustments that should be made on

the cutter deck: pitch and height.

PITCH is the angle of the blades (comparing front

to rear).

HEIGHT is the nominal distance that the blade is

off the ground. This measurement is made with the

blades pointed side to side and distance is measured

between cutting tip and ground.

2. To adjust cutter deck drive belt: Adjust the nut so

that the belt moves 1/2" with 10 pounds of pres-

sure. (See Figure 7).

Adjusting the blade height can be done by moving any

number of the five smaller spacers on the blade mount-

ing bolts to the top or to the bottom of the spindle shaft.

All blades should be positioned equally (See Figure 10).

The unit is shipped with one spacer on top of spindle

and four underneath (See Figure 10).

This adjustment does not affect blade pitch.

-NOTE-

For best results, keep the cutter deck

high in relation to the engine deck and

the blades low in the cutter deck; ie. 4 or

5 spacers below the spindle shaft.

Additional range to the cutting height can be

achieved by repositioning the cutter deck in relation-

ship to the engine deck. This adjustment also affects the

pitch of the deck.

Figure 10. Cutter Blade Adjustment

There are three positions for mounting the cutter deck

(See Figure 11). For cutting in the lowest position,

mount the cutter deck in the top hole (A). For cutting

in the highest position, mount the deck in the lowest hole

(C). Setting the cutter deck height will be determined

by the type of cutting conditions.

Caster spacers also can be repositioned to change the

cutting heights and to change the pitch of the deck (See

Figure 12).

To adjust the caster spacers, raise the deck and remove

the pin and caster wheel. Reposition the caster spacers

as needed, then replace the caster, top spacers and pin.

Make the same adjustments on the other caster wheel.

To adjust the blade height, move any number of the five

1/4" thick spacers on the blade mounting bolts to the

top of the spindle shaft or below the spindle shaft.

A. 3" Position - baffle is installed using the top set of

holes on the front baffle welded inside the cutter

deck. (See Figure 15). The Advantage cutter deck

will deliver the best quality-of-cut in very tall, wiry,

tough to cut grass.

B. 3-1/2" Position (factory setting, Advantage Deck) -

baffle is installed using the middle set of holes on the

front baffle welded inside the cutter deck. (See

Figure 16). For general purpose cutting, place the

Custom-Cut Baffle in the 3-1/2" position. This gives

the best mix of cutting performance in all types of

grass.

C. 4" Position (factory setting, Velocity Plus Deck) -

baffle is installed using the bottom set of holes on the

front baffle welded inside the cutter deck . (See

Figure 17). Placing the baffle in the 4" setting will

enhance fall cutting (leaf pickup) and reduce cutter

deck "blowout".

To adjust the Custom-Cut Baffle height:

1. Place the cutter deck in the transport position.

2. Remove the hardware securing the Custom-Cut

Baffle to the cutter deck. (See Figure 14).
